dd is deprecated? I'm surprised. I use it all the time. It's great when
a blocksize of 512 is too slow, like for large files onto slow backup
disks or network transfers, I might use dd bs=10240 or some such thing.
I suppose the block size on Linux might be bigger these days, but the
command is still standard.

it seems like 'dd' was non-unixy in it's design approach, if I'm to

the lores around, which leads me to think that this might have been another
one of the many idiosyncratic naming conventions used back then. More on
the dd stuff: http://www.catb.org/jargon/html/D/dd.html
As noted in the jargon
file, the dd(1) syntax is deliberately reminiscent
of the DD statement in IBM JCL. This was presumably a joke and one of the
BTL old-timers on the list may know more of the background.
